WORKBENCH.

Application filed March 18, 1925.

To all whom it may concern Be it known that we, O'rrro JOHN Youno- MANand MAXIMILIAN R. YOUNGMAN, citi- ZGIIS of the United States, residingat Los Angeles, in the county of Los Angeles and State of California,have invented new and useful Improvements in lvorkbenches, of

which the following is a specification.

This invention relates to work benches. An object of the invention is toprovide readily adjustable means incorporated in the work bench forholding strips of material such as wood, for planing, sandpapering andthe like, and to facilitate acco1nn1oda tion of the holding means toobjects of greatly varying width.

A further object is the inclusion in :1 de vice of the type described ofa vise arrangement which is quickly adjustable to any extension limitedapproximately only by the length of the work bench and to enable a boardor other object being held in the vise to at the same time rest upon thetop of the work bench. I

Other objects and advantages will be made manifest in the followingspecification of an embodiment of the invention illus-- trated in theaccompanying drawing, in which- .Fig. 1 is a perspective of the workbench,

Fig. 2 is a top view of the work bench,

Fig. 3 is a fragmentary vertical section of a portion of the work benchtaken. on the line 33 of Fig. 2.

Fig. 4 is azfragmentary vertical section of a portion of the work benchtaken on the line 414 of Fig. 2, i

Fig. 5 is a fragmentary vertical section of the work bench and visearrangement taken on the line 5-5 of Fig. 2, i

Fig. 6 is a fragmentary view of the side of the work bench top taken inthe direction of the arrow 6 of Fig. 2,

Fig; 7 is a horizontal sectional 'fraginen tary view of the portion ofthe work bench shown in Fig. 6 and is taken in the direc tion of thearrow 7 of Fig. 6.

The details of constructionand operation of the invention are as followsA work bench top 10 is supported by suitable legs or standards 11 whichare properly placed with end pieces 12 and side pieces 13; thesupporting frame work may constitute any desired structure. T v

The top 10 is approximately rectangular Serial N0.'1,6,383.

which is disposed vertically and is parallel to the side 1 A wedge blockwhich is herein. shown as rectangular in design and of sufiicientthickness'to provide a substantial obstruction is provided with adiagonally disposed tongue 21 which is adapted to slidably engage one ofthe grooves 14:, 15 and 16 and the wedge block to slide over the surfaceof the upper face of the top. It will be noted that the sides of'thewedge block are.

parallel to the sides of the top 10 and that the guide-way formed by thegroove 16 will cause the wedge block to be moved to or from the sideofthe top when the block is slid lengthwise in the groove.

A slide block 22, having a substantially U shapedcross section isadapted to slidably engage the side 18 of the top 10 and an upperextension 23 to slide on the upper face of the top and a lower extension24 to slide on the lower face of the top. This slide block is formedwith a tongue 25 adapted to slide in the groove 1'? and the lowerextension is provided with a tongue 26 which is adapted to slide in thegroove 19. It will thus be observed with reference to Figure 3 that thecooperating tongues 25 and 26 act to prevent the slide block 22 frombeing moved in any direction except longitudinally of the side of thetop. Thus the inner face 27 of the slide block presents a substantiallyrigid abutment between which and the wedge block 20, a piece of materialmay be wedged and held securely for being worked.

The side 18 has a plurality of recesses 28 into which a pin 29 operatingthrough the slide block 22 is adapted to project for the purpose ofsecuring the slide block against lengthwise movement. posed at the endof an arm 30 which ispivoted between a pair of ears 31 and has a The pin29'is dis handle/32c at its opposite end A short lug 33 projectingoi-itward-ly from the'slide block 22 is adapted to retain an ezq ansioncoil spring 34- which bears at one end on the slide block and at itsother end onth'e arm 30. Thus the pin 29 is normally pressed. inwardlyto effect an engagement with one of the apertures 28. The pin 29however,

may be locked in an optwardor disengaged position by means of a swinginglock member which is adapted to he intenposcd be tween the arm 30 andthebl'ock and to otler an obstruction-to .the said arm, preventing thepin from entering any oi the apertures.

A block 236'- is formed with a cross section substantially identical tothe cross section of the slide block .22 and is adapted to slide uponthe side of the top and its tongues and 38 to engage the grooves 17 and19: respectively. Oine end of the vise block 36 has arecess 3.) intowhich the hearing cud 4-0 ota-jack screw-{L1 is adapted to work, Thebearings-2nd li'is formed with an annular groove 42 in which a set screw$1 3 is adapted to be extended lor preventing retraction-oi thejaokserew 41 from the vise block The jack sore-w i1 is threaded throughan extension is at the end of the top and, a crank 45 is provided at theouter end of the jack sore-w.

- The operation oil'the invention may be understood as follows:

A board'strip oat" material or other object which is to be worked may belaid iupon the top of the work bench and one edge brought adjacent theface 27 of the slide block 22. An approximate adjustment may be etleetedby inserting the tongue 21 on the wedge block 20 in the pnoper one ofthe grooves 14: 15 and16. A more minute adjustment as to operation bythe slide block 22 and the wedgeblock may be effected on releasing thepin 29 from its position in one ofthe recesses 28 by means of the handle32 on the ar1n30-and the slide block 22 may he slid along theiside 18 ofthe top 10 to the desired position. The object may then be tightlywedged between-the two blocks by pushing the block 20 in the directionwhich will cause the said block to draw nearer to the side of the'itop.The object may be released by arring the wed-geblock 20 in the oppositedirection which willhavethe efl'i-mt of pulling the said wedgebloek.away from the object being held. The USG' Oflth-G vise arrangementcontemplates cooperation betweenvthe slide block 22- and the vise block36. The lirst approximate adjustment may he made by disposing the slidebloek'22 in the desiredpositionwalong the side 18' and the pin 25 shouldhe allowed to enter one, of the rocessesQ-S tothci'cby secure the slideblock lVhatever =worked on :shouikl placed against the upper extension23 of the slide block 22 and may be tested upon the top or otherwise andthe vise block 36 tightened against the object by rotating the crank onthe jack screw il-1.
